Bi-metal thermometers use a long probe (the stem) to transfer the heat to a coil just behind the dial which expands or contracts according to the temperature it is exposed to. The dial of the bi-metal thermometer then displays the temperature.
Our range of Bi-metal thermometers caters for all applications and industries as well as home use. The Bi-metal thermometer is durable and has a wider temperature range then many other thermometers.

A no frills basic thermometer. Good clear display and easy to use.

Accurate. But springs a little fiddly.

I am happy with this, it does the job - However, if the back was even slightly concave instead of flat so it sat on the pipe, to make a better contact point, it would respond a bit quicker. However - For the money - A very decent unit. (2 different length springs supplied - Good!)
